Romeo can't see HDXL programs on network

I added a Romeo Plus to my home network two days ago, and can't view the programs on my older HDXL from the newer Romeo. The network connection comes into the house through a cable modem, then through an Apple Airport Gigabit router, and then to an Asante FS5008c 10/100 switch. Both Tivo's are fed from the Asante switch, and show up in the Now Playing list on the other Tivo. However, while I can see the recorded programs on the Roamio from the HDXL, I cannot see any of the programs on the HDXL from the Roamio. Instead, I get an error message that "a network error has occurred." I have verified that both Tivo's have an active internet connection by connecting to Tivo central and by streaming Netflix.

This happened to me as well until I forced the old TiVo (in my case a TiVoHD) to call into TiVo service. Then it "sees" the new TiVo as allowed. The "a network error has occurred" message is deceiving.
